🎵 Scaler Detector——独立运行版及 VST/AU/AAX 插件，专为识别你演奏内容的调性而打造。可侦测整首歌曲、复音音频轨道或原始 MIDI 流的调性。

🎯 Scaler Detector 可以用来做什么？

调性、音阶与和弦侦测

搭载与全球人气乐理插件 Scaler 3 相同的强大调性与音阶侦测引擎，Scaler Detector 可即时识别任何音轨、Loop 或现场演奏的调(Key)、音阶(Scale)及和弦(Chord)。支持实时输入音频或 MIDI，也可拖入文件即刻得出结果。

试奏和弦 & 探索和弦替代方案

侦测到调性与音阶后，可将琴键绑定为一指按和弦(One-Finger Chords / Bind to Keyboard)，让和弦完美贴合你的音乐；或直接搜索音阶并开始跟弹。开启声部编组(Voice Grouping)可实现自动声部导进(Voice Leading)，使和弦听感更丰富、更具音乐性。
